Hello! I am running XP Pro. Something is generating the same file [which appears to be a program, in Notepad] over-and-over at startup. It can only be deleted in Safe Mode [access denied in normal windows]. "~DF123.tmp" is an example. The number in the filename changes, but the "DF*.tmp" is always the same. In file Properties, there is no info on the app it is associated with or the company of origin. It is listed as "unknown application". Is there any method I can use to trace the origin of this file to the app that is generating it? Thanks.
